CA Forum: Charts and Graphs
My report starts with a chart in page 1 and then page 2 will start with data as below. The chart in page 1 is based on the data below.
AlarmTime Details Zone -
(dd/mm/yyyy hh:mm:ss) XXXX XXX
The report captures data from a SQL table. The user can filter the report shown based on selections: 1) Start Date 2) Range of Date, ie Daily, Weekly, Monthly, Yearly
Descriptions: 1) Start Date is the selection of starting date of AlarmTime. 2) a) Daily - show the records on "Start Date" only. b) Weekly - show the records from "Start Date" to "Start Date + 6 days" c) Monthly - show the records from "Start Date" to "Start Date + 30 days"
Other than that, a chart showing the number of records on the first page is required based on the selection of 1) and 2). The table of data will start from page 2.
If user selects 2)a) Daily, the chart will show the hourly number of records. That means the y-axis is number of records and x- axis will be 1st hour, 2nd hour, 3rd hour, ... , 24th hour.
If user selects 2)b) Weekly, the chart will show daily number of records. Y- axis is number of records and x-axis will be day1, day2, ... day7
If user selects 2)c) Monthly, the chart will show weekly number of records, Y- axis is number of records and x-axis will be week1, week2, week3 and week4.
That means the chart is created on run-time based on user's selections.
I can't figure out how to create the chart. My problem is how to get the number of records for 1st hour (Start Date 00:00:00 to Start Date 00:59:59), 2nd hour (Start Date 01:00:00 to Start Date 01:59:59) and other hours and then, show on the y-axis of the chart. I checked through "COUNT" function but it doesnt work that way. I also thought of using SQL query, ie . Select COUNT(*) from ALARM where AlarmTime between ...". However, it doesnt make sense because the StartDate is determined on run-time by user. Apart from that, i also can't find out the number of records in day 1, day 2... day 7 if user selects "WEEKLY". Anybody has any idea in this?
My other question is whether the chart can be drawn dynamically in crystal report in "Daily" form, "Weekly" form or "Monthly" in run- time.
